Comparing numbers

We are going to be spending some time building larger numbers and comparing them.  Today we started by building number trains and comparing which train had more and which train had less. Then we chose the correct symbol to use to show what we had discovered and we used the App explain everything to share our thinking. You can click the link below to view a sample of the thinking and teamwork involved! Enjoy!
